ROBERT M. JORDAN, OF COOPER, TEXAS.

PISTON -RING.

.ppllcation filed February 18, 1819.

To all whom. it may concern Be it known that I, Ronnu'r M. JORDAN, a citizen of the United States, residing at Cooper, in the county of Delta and State of Texas. have invented a new and useful Piston-Ring, of which the following is a. specification.

This invention relates to metallic piston rings such as used in the pistons of hydrocarbon engines and the like, and it is more especially an improvement upon the joint structure, whereby expansion and contrac tion on the ring is permitted without leakage. An object of the invention is to provide a one piece concentric ring which will form an efiicient seal at the joint and which has means whereby surplus oil will be collectcd during the reciprocation of the piston either for preventing it fronrentering the combustion chamber of the cylinder in excessive quantities or for facilitating the lubrication of the piston, according to the position and location of the rings on the plston.

\Vith the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claim, it being understood that various changes may be made in the construction and arrangement of the parts without d'e parting from the spirit or sacrificing any of the advantages of the invention as set forth in the appended claim.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings: Figure 1 is a plan View of the ring. Fig. 2 is a side elevation thereof. Fig. 3 is a section on line 3-3, Fig. 2. Fig. 4 is a section on line 4-4, Fig. 2. Fig. 5 is a perspective view of one end of the ring.

Fig. 6 is a similar view of the other end thereof.

Specification of Letters Patent.

Serial No. 277,781.

Fig. 7 is a section through the lap in portions of the ring and showing a modi fie form of opening therethrough.

Referring to the figures by characters of reference 1 designates the body of the ring and the ends of the ring are cut away diagonally as at 11 to prodnce a long miter joint extruding through approximately one 'quarter thc circumference of the ring. The

eesses or. openings can be provided. These openings serve to collect surplus lubricant and prevent it from working into the cylinder under some conditions. l nder other conditions the recesses will carry anddistribute lubricant to insurenniform lubrication of the piston to which the ring is applied.

lVhat is claimed is:

A piston ring formed in one piece and having elongated tapered beveled ends disposed in lapped relation, there being a bevel extending along one edge of the outer face of the ring and provided with depressions constituting oil aecumlating and distrihut. ing means.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
